FUN COMPARISONS AND DESCRIPTIVES IN ENGLISH LANGUAGE...

Proverbs have a long history. Many of them stretch back to Chinese Dynasty origins. There are others that are more 'modern' but still sound like ancient and wise sayings.  Here are a couple that speak to knowledge and wisdom..

"He who knows and knows that he knows, is a wise man. Follow him."  

AND

"He is the only one who knows as much as he thinks he does." 

 --- I am not sure about the truth in these,  but I'm certain about the intent.  It's an important distinction because proverbs are held as being a 'universal truth'. After all, they're proverbs for a reason ... even if we don't agree with them.
